    摘要: A magnet-embedded rotor that increases the torque of a motor and reduces the torque variation in the motor and an orientation magnetization device for the rotor are provided. An orientation magnetization device (60) includes plural orientation magnetization yokes (62) and plural orientation magnetization magnets (61), and molds field magnets while a rotor core (40) is disposed in a magnetic circuit that is formed by assembling the orientation magnetization yokes (62) and the orientation magnetization magnets (61) into an annular shape. When the rotor core (40) is disposed in the magnetic circuit such that an outer peripheral surface of the rotor core (40) faces an inner peripheral surface of the orientation magnetization device (60), protruding portions (62a) are disposed at portions of the respective orientation magnetization yokes (62) facing the rotor core (40). Auxiliary magnets (63) are disposed in gaps between the respective orientation magnetization magnets (61) and the rotor core (40), on opposite sides of each protruding portion (62a) in a circumferential direction of the orientation magnetization device (60). Each protruding portion (62a) and each auxiliary magnet (63) extend in an axial direction of the orientation magnetization device (60), and are skewed with respect to the axial direction of the orientation magnetization device (60).

    摘要: According to an embodiment, a permanent magnet rotating electrical machine (100) has: a rotor shaft (11) which is rotatably supported and extends axially; a rotor core (12) fixed to the rotor shaft (11) and has a laminated plate including steel flat plates laminated axially; permanent magnets (41a, 41b); a stator core (21) disposed on an outer periphery of the rotor core (12) with a gap (25); and armature windings wound around the stator teeth (22) of the rotor core (12). The flux barriers (31a, 31b) are formed in each circumferential angle region so as to extend axially, spread circumferentially toward the rotation axis center in a convex curved shape. A permanent magnet space (13a, 13b) is formed in a circumferential direction center portion of each of the flux barriers (31a, 31b). The permanent magnets (41a, 41b) are disposed in the respective permanent magnet space (13a, 13b) in which demagnetization resistance monotonically decreases from the outside to the inside in a radial direction between permanent magnets (41a, 41b) adjacent to each other radially.

    摘要: A magnet constituting a magnetic pole 3 of a rotor 100 includes an annular ferrite bond magnet 1 provided on an outer circumference of a rotation shaft 4 and a plurality of sintered ferrite magnets 2 arranged on an outer circumference of the ferrite bond magnet 1. The ferrite bond magnet 1 includes, on an outer circumferential surface thereof, curved concave portions 1a that are formed at a regular pitch on the same circumference along a circumferential direction and are convexed toward a side of the rotation shaft 4, and the curved concave portions are formed so that the number thereof is identical to the number of the magnetic poles 3. Each of the sintered ferrite magnets 2 is arranged on each of the curved concave portions 1a; and includes a surface on a side of the stator that is formed in a curved convex shape toward the side of the stator, a surface on the side of the rotation shaft that is formed in a curved convex shape toward the side of the rotation shaft and in a shape substantially identical to each of the curved concave portions 1a, and a center portion whose thickness with respect to the circumferential direction is formed to be larger than thickness of an edge portion, wherein magnetization direction is oriented in polar anisotropy.
